Replying to Smoking after blackout freaks me out. please help!!!

I've been smoking for 2 years regularly and 2weeks ago I blacked out after smoking a few blunts in a shower (i smoked much more than that before, so it was really unexpected but thats not the point of this thread). It was super fucked and I felt really weird like i coyld constantly feel my mind about to go down or some shit.

I wasnt too worried, i thought i must have been a one time type of thing and i smoked again tje day after that and it was fine.

Yesterday tho i smoked a little (not even one full joint) and all of a sudden i get this fucked up feeling and i know instantly that its the same one i got before and during my trip/blackout. I was so freaked out cos i dont want that shit to happen again ever that i almost felt line crying (fucked right? And i only drank a beer before that).I ran away from anyone with weed and laid down for a while. After a few minutes i was fine but i was so fucking scared of smoking more cos of that fucked up feeling i got.

Again, its been over two years and this never happened. Its hard to describe the feeling i got, but its very differeng from the normal high feeling i get, like trying to fight against yourself while your mind just keeps fucking with you and feeling just fucked.

Cant be the weed, (could be for my blackout) its the same one i've smoked for a while and i know its pretty great.

So if you could help me out here it be great,i dont know what to do, i hope that i can smoke again and be like it used to be... wtf happened that makes me super freaked out on half a joint when i used to smoke 5 blunts an evening regularly for a long time???
